Radar level gauge suppression issue?
Thread Content
Is the height at which cable radar and flared-radius radar perform suppression the radar flange–level height (rod measurement height)?
I don’t know what kind of radar you’re using. The most commonly used for interference suppression are radars installed on waveguides. Generally, it is best to perform interference suppression when the tank is empty. For example, when the bottom-of-tank reflection is at 10,000 mV, the several 1,000 mV noise components present in the entire waveform can be suppressed by raising the base voltage to 1,300 mV. Using paid services for interference suppression has one drawback: after the process is completed, if the liquid level drops, it may be necessary to repeat the procedure. Because when you perform effective interference suppression, it’s not possible to do it below the liquid level.

It’s really troublesome; it’s like having to urinate through a bubble. You need to use a small knife to cut the foreskin off. If you don’t use the knife to do that, you can’t urinate, right? {:2_42:} Look at how skilled you are with the ball, you idiot, crazy guy, you worthless wretch.
The e+h radar level gauge, with a guide wave tube, isn’t connected to any debugging software. I can see an interference signal above the liquid level on the envelope curve; when attempting to suppress this signal manually on the gauge, should the suppression level be set to E – L – 0.5m? Should we just use the ruler measurement of -0.5m?
Use an altitude of -0.5 for suppression. It is the distance from the flange edge to the bottom of the tank minus 0.5
I’m not too familiar with e+h. Rossmont’s radar has an option related to waveguides – choosing the wrong one makes it almost impossible to use the device, as it’s not possible to view the waveforms. Check if e+h has this option. If the reflection intensity of the liquid level is more than twice that of the interference wave, the interference can be ignored; generally, the system will intelligently identify the strongest signal as the liquid level.
